Abstract

The invention relates to an arrangement for cooling electrical subassemblies arranged in a housing, in particular for use in base stations of a mobile radio system or access network system. The arrangement has at least one water-repellent membrane filter, in each case arranged in an air inlet of the housing, for the surface filtration of dirt particles from cooling air flowing in for cooling electrical subassemblies, as well as at least one cooling device to build up an airflow and to lead the filtered cooling air, heated because of flowing through the subassemblies, out of the housing through at least one air outlet.
